AT91SAM9XE256 - ATMEL Corporation

AT91SAM9XE256 (AT91SAM9XExxx) AT91 ARM Thumb Microcontrollers

The AT91SAM9XE128/256/512 is based on the integration of an ARM926EJ-S processor with fast ROM and RAM, 128, 256 or 512 Kbytes of Flash and a wide range of peripherals. The embedded Flash memory can be programmed in-system via the JTAG-ICE interface or via a parallel interface on a production programmer prior to mounting. Built-in lock bits and a security bi.
